Why isn't my super simple program not working???

I did a google search and was shown code that I essentially copied directly. Here is my code:

Code:

---

Imports System.Net.Http

Module Module1
    Private ReadOnly client As New HttpClient()

    Sub Main()
        Dim response = GetStockPrice("AOA")
    End Sub

    Async Function GetStockPrice(ticker As String) As Task
        Dim baseUrl As String = "https://api.api-ninjas.com/v1/stockprice"
        Dim url As String = baseUrl + "?ticker=" + ticker
        Dim apiKey As String = "MyAPIkey"

        Try
            Using request As New HttpRequestMessage(HttpMethod.Get, url)
                request.Headers.Add("", apiKey)

                Using response As HttpResponseMessage = Await client.SendAsync(request)
                    response.EnsureSuccessStatusCode()
                    Dim responseBody As String = Await response.Content.ReadAsStringAsync()
                    Console.WriteLine("Response Data:")
                    Console.WriteLine(responseBody)
                End Using
            End Using
        Catch ex As HttpRequestException
            Console.WriteLine($"HTTP Error: {ex.Message}")
        Catch ex As Exception
            Console.WriteLine($"General Error: {ex.Message}")
        End Try
    End Function
End Module

The code compiled without issue, but when I ran it, nothing appeared on the console. So, I figured I would step through the program, but for some reason, the program exits when it hits the 'using response' line. I double-checked the api-ninja documentation and I do have the header correct.

To double check, I then added an extension to Supermium that allows setting headers. I added the APIkey header, entered the URL in the address bar, and got a proper response. What is wrong with my code?

Code:

---

request.Headers.Add("X-Api-Key", apiKey)

---

Stupid moi - I copied/pasted incorrectly - "X-Api-Key" is actually there.

Your main method is calling an asynchronous method without using the await keyword. If you cannot make it async (e.g. it is the starting point of your application), then get the result of the task:

Code:

---

GetStockPrice("AOA").GetAwaiter().GetResult()

The response I got from your URL using an API key was:

Code:

---

{"ticker": "AOA", "name": "iShares Core 80/20 Aggressive Allocation ETF", "price": 96.14, "exchange": "AMEX", "updated": 1780949590, "currency": "USD", "volume": 89163.91758}
